"Generic type 'AggregateQuerySnapshot<T>' requires 1 type argument(s)."

My Angular app won't compile with rxfire 6.0.5. The error is

Error: node_modules/rxfire/firestore/lite/interfaces.d.ts:8:29 - error TS2314: Generic type 'AggregateQuerySnapshot<T>' requires 1 type argument(s).

 8 export type CountSnapshot = lite.AggregateQuerySnapshot<{
                               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 9     count: lite.AggregateField<number>;
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
10 }, any, DocumentData>;
   ~~~~~~~~~~~~~~~~~~~~~

This is with Firebase 9.23.0. I can't get Firebase 10 to work, see my StackOverflow question.

Why is rxfire trying to use Firestore Lite? I never imported anything from firebase/firestore/lite.

Same issue, I temporarily fixed it by forcing it to 6.0.4.

Same issue here while using @angular/fire - fixed by installing rxfire 6.0.4 too.

Same issue here with @angular/fire but in my case installing rxfire 6.0.4 didn't help. I tried to install 6.0.3 because this was my previous version in package-lock but it didn't help too so I had to restore my whole previous package-lock where I use rxfire 6.0.3, so probably some other package makes issue too

I think the issue here is that rxfire@6.0.4 introduced a breaking change and now requires firebase@10 to function. So sticking to rxfire@6.0.3 with firebase@9 is the solution.

Adding this override to package.json resolves the issue for me:

{
  "dependencies": {
    "@angular/fire": "~7.6.1"
  }
  "overrides": {
    "@angular/fire@~7.6.1": {
      "rxfire@^6.0.0": "6.0.3"
    }
  }
}

  }
}

I had commented about my temporary fix by forcing my app to use 6.0.4 but this is more reliable solution.

I was getting unexpected firebase integration errors such as "FirebaseError: Firebase: No Firebase App '[DEFAULT]' has been created - call initializeApp() first (app/no-app)". Then I tried to force 6.0.3 and these errors are also solved.

Thanks rgant.
